CHU'IE-OPERATING MEANS.

Application filed February 26, 1923.

To all whom it may concern:

Be it known that I, WALTER STELTER, a citizen of the United States, residing at Echo, in the county of Yellow Medicine and State of Minnesota, have invented new and useful Improvements in Chute-Operating Means, of which the following is a specification.

This invention relates to an attachment for thrashing machines, the general object of the invention being to provide means for taking up the slack in the hood operating cables as the chute is adjusted longitudinally.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, ref-- erence will be had to the accompanylng drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view showing a straw chute and hood with the invention in use.

Figure 2 is a side view.

Figure 8 is a perspective view of the forked member 10 Figure 4 is a perspective view of the bracket 1.

Figure 5 is a view of the single pulley 6.

Figure 6 is another view of this pulley.

Figure 7 is a view of a modification.

As shown in these views I secure a bracket 1 to the support 2 for the endless chain 3 of the telescoping means, said bracket hav ing a hook 4 thereon to which is attached a double pulley 5. A single pulley 6 is connected to one of the links of the chain 3 by a T-shaped part 7 so that the pulley will travel with the chain. The cable A for rotating the hood has its ends attached to the hood at opposite sides thereof, as shown at 8, and after passing over the pulley 9, said cable is passed through the double pulley 5 and has its central part engaging the pulley 6. The forked member 10 is slidably mounted on the bar 11 which forms part of the means for raising and lowering the chute, said member being held in adjusted Serial No. 621,350.

position on said bar by friction, and said member is provided with a hook 152 which supports a pulley 13 over which the rope B for raising and lowering the hood passes. The end of this rope is connected with the eye of the pulley 6, as shown at 14.

From the foregoing itwill be seen that when it is desired to rotate the hood in one direction one part of the rope A is pulled upon and when it is desired to swing the hood in the opposite direction the other part of the rope is pulled upon. When the hoodis to be raised the member 10 is moved towards the handle end of the bar 11, thus pulling upon the cable B to raise the hood. By moving the member 10 in the opposite direction the hood will be lowered. As the loop in cable A and the end of cable B are carried by the pulley 6 it will be seen that both cables will be tight as the chute is projected and retracted through the movement of the endless chain. Thus it is not necessary to tie and untie the cables, as is usually done, in order to prevent slack in said cables when the chute is actuated.

In some thrashing machines the bar 11 is not used and in this case I would use the bracket, shown at 15 in Figure 7, this bracket being formed with the hook 16 for receiving the double pulley 5 and having a reduced part for receiving the slide 17 which is provided with a hook 18 for receiving the pulley 13, this slide 17 taking the place of the member 10. This bracket is substituted for the bracket 1. In other respects this form of the invention is similar to that be fore described.

It is thought from the foregoing descrip tion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

lVhat I claim is The combination with a wind stacker chute and its hood and the cable for actuating the hood to swing the same to the right or left and the cable for raising and lowering the hood and the telescoping means of the chute which means includes an endless chain, of a stationary bracket secured to the chute adjacent the inner end thereof, a double pulley carried by said stationary bracket and over Which the cable for swinging the hood passes, a second pulley connected With one side or" the endless chain and receiving the loop of the first mentioned cable, a slidable member, a pulley thereon and over which the cable for raising and lowering the hood passes, and said last mentioned cable having its end connected with M the pulley on the chain.

In testimony whereof I ZiifiX my signature.

WALTER STELTER.
